新型吡啶双羧酸席夫碱配体锌配合物的合成、晶体结构及荧光性质(英文)

Synthesis,Crystal Structure and Photoluminescent Property of a Zinc(Ⅱ) Complex Based on Novel Pyridyl-dicarboxylate Schiff-Base Ligand

A novel pyridyl-dicarboxylate Schiff-base ligand (5-((pyridin-3-ylmethyl)amino)isophthalic acid,H2L) and its Zinc(Ⅱ) complex,namely,ZnL (1),were synthesized. The ligand was characterized by NMR analysis. The X-ray crystallographic analysis on complex 1 shows that 1 crystallizes in homoclinic,space group P21/c with a= 0.753 83(10) nm,b=1.040 52(14) nm,c=1.734 67(19) nm,β=112.123(5)°,V=1.260 5(3) nm3,Z=4,Dc=1.769 g· cm-3,F(000)=680,μ=1.966 mm-1,the final R=0.030 8,wR=0.085 6. In complex 1,the coordination environment of Zn(Ⅱ) is distorted tetragonal-pyramid with N1O4 set. The 2D 4,4-topological sheets in 1 packed along a axis to form its 3D framework,which was stabilized by the π…π interactions between the adjacent aromatic rings on the neighbouring sheets. The photoluminescent property of 1 was also investigated.
